START-UP
NOTE! Follow the recommended procedure in the order shown.
CAUTION! The Start-up procedures assume that all of steps in Proportioner
purging have been performed and no problems found.
1. Check the hydraulic fluid level and service as required.
2. Make sure the materials have been stored at the manufacturer's recommended
temperature. Ask your material supplier for information (Material Data Sheet) on the
minimum storage temperature.
3. Y-Strainer screens should be checked routinely.
4. Connect air supply to the two Transfer Pumps and ensure Air Valves are in the full
OPEN position. OPEN both Proportioner Material Inlet Ball Valves.
CAUTION! Remove all Heated Hose sections from coiled storage and lay flat
to eliminate heat build-up and possible Heated Hose failure.
5. Turn ON Main Power [P page 12].
6. Turn ON Control Power [R, page 12].
7. Turn ON Hose [S, page 12]. Heater and confirm material set-point temperature as
recommended by the material supplier or application conditions.
CAUTION! To avoid excessive pressure in the Proportioner, wait for the Hose
Heater to reach its set-point temperature before continuing.
8. Turn ON each Primary Heater and confirm material set-point temperature as required by
the material supplier or application conditions has been reached.
9. Turn ON Motor Power [X, page 12].
10. Set Pump Switch [Y, page 12] to NORMAL. One of the Directional Indicator Lights [Z,
page 12] will light indicating Metering Pump direction and the Metering Pump Shafts will
begin to move.
NOTE!
a. The Material Pressure Gauges [H, K, page 9] should be approximately equal and
remain constant throughout Metering Pump cycle. If not, refer to Trouble Shooting
section.
b. Directional Indicator Lights must indicate Metering Pump direction when Pump
Switch is in the NORMAL position. If not, refer to Trouble Shooting section.
11. Using the Hydraulic Pressure Control, adjust to the required stall pressure and check
each Material Pressure Gauge.
. Stall pressure: When materials are at recommend application temperature and Metering
Pumps are pressurized but not moving. This pressure is normally 100 – 200 psi greater than
the developed spray pressure as recommended by the material supplier.
